Abstract
The cooling system includes a series of cooling channels arranged to provide convective cooling, with inserts for shielding electromagnetic interference (EMI) that is propagated by the waveguide nature of the cooling channels. Due to the relatively open nature, the cooling channels can serve to propagate EMI energy. The inserts mitigate the EMI exiting via these channels by attenuating or blocking the EMI. The inserts are shaped to block particular frequencies of EMI. The inserts may include thin sheet metal contoured to a half-wave profile, arranged along each cooling channel.
